Contacted 3 dive ops: Scorpio, Alvaro at Always Diving and Solo Buceo. We were on a short lead time, so went with the first reply. All of the shops replied within 24 hours.
Used Scorpio Divers. Pretty much a little hole in the wall with a shared hut out of the Sotavento hotel. Whole group was friendly. Alfredo was our DM and he was perfectly fine and friendly. In our two days of diving it was always 4 divers on the boat. Boat was old but in good shape, plenty of shade and the motors looked new. There were never any problems with the boat or crew. We used our own gear, but the rental equipment used by others looked to be new and in excellent shape.
We dove the local reef, no more than a 20 minute boat ride once out of the harbor. Saw other boats, but never other divers. Location was limited by us because we did not have the time to get to Cozumel or other sites further south.
Our first drift dives. Man, the O2 goes fast if you get caught out and have to fight the current at all!
Tons of fish, mostly hiding below the edges.
